Revision history [back]

Now, I place my solution here:

1.make a new directory and navigate to it, then create a new document.

$ sudo mkidr -p /etc/ros/rosdep/sources.list.d
$ cd /etc/ros/rosdep/sources.list.d
$ sudo gedit 20-default.list

2. go to the link https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list 3. copy the contents from the link to the 20-default.list. which may like this:

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx   
# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte   
# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro 
index.yaml instead

4. replace the all the raw.githubusercontent.com to raw.github.com in 20-default.list document, then save and close it. 5. run rosdep update
